One of Nicola Sturgeon's main message to listeners in today's Q&A is calling on them to support her if they want to stop Boris Johnson being elected.

She takes a question from Robert, in Glasgow, who asks "where would we be left legally" if Westminster refused another independence referendum.

"I'm not going to get dragged into the whys and wherefores of that," she replies. "I want to focus on stopping Boris Johnson getting a majority."

But she adds that "I've accepted the need to have that proper legal process" - although adds that it has "never been tested in court".

BBC presenter Nicky Campbell asks whether she'd follow the Catalan example and hold an unofficial referendum, but our political correspondent notes that she's not keen.

As we listen to Nicola Sturgeon, a reminder that Conservative leader Boris Johnson, Plaid Cymru's Adam Price and the Greens' Jonathan Bartley have already made appearances in a Q&A like this.

Brexit Party leader Nigel Farage is up tomorrow, but 5 Live presenter Rachel Burden tweeted last night that the station was "still waiting for confirmation" from Labour's Jeremy Corbyn that he would take part.

The next question comes from a woman in the Isle of Skye, who asks how SNP leader Nicola Sturgeon could ensure the independence for Scotland that she seeks wouldn't leave the country in "limbo", like the vote for Brexit has.

Ms Sturgeon says that's "a really good question", and goes on: "I don't think we should allow the mess we've made of Brexit to [allow us to] assume that all change has to be like that."

She says that while she opposes Brexit, "there was nothing inevitable about the mess that it's become."

She argues there should be a "frankness" about people accepting that there is a degree of uncertainty about the future.

"Being independent is not a guarantee that the country won't have rocky times... but it means we are in charge of how we get through that."

Nicola Sturgeon, the leader of the Scottish National Party, is answering the public's questions during an hour-long Q&A live on BBC Radio 5 Live and the BBC News Channel.

The first question comes from Lyeona in Galashiels who asks whether she could "behave with maturity and put the interests of the whole country" above wanting an independence referendum in the event of a hung Parliament.

Ms Sturgeon replies: "Yes I will, if we're in that situation, put the interests of the whole of the UK at the heart of what we do".

She says since the Brexit referendum the SNP has tried to "make common cause" with other parties.

"I want to see the whole UK get the opportunity to escape the mess."

But she adds that if another party wants the support of the SNP after the election, then she hopes their leader will "respect" that they want a fresh independence referendum.

We know that millions of commuters have been told they're going to have to pay an average of 2.7% more for rail tickets from 2 January.

Now we have the promise from Labour to cut regulated fares by one third - that's season tickets - and fares for under 16s.

We're talking about roughly 45% of all fares that are produced.

It is, though, worth saying that the Labour manifesto simply says "we'll make fares simpler and more affordable."

Labour insists it will all be paid for very carefully, in this case by "repurposing" existing funding.

But there is a lot of spending that is not set out in their book of costings - the Waspi women pledge too, for example.

Another sidebar on this, obviously if Labour is to implement any of this it needs to be government.

The best chance of doing that, although we don't know for sure, appears at this stage to be at the head of a minority government, perhaps with issue-by-issue support from the Scottish National Party.

But on rail renationalisation, the SNP don't like Labour's policies. They want more power devolved to Scotland.

So if we do get to political negotiations in the event of a hung Parliament, it is worth remembering there will plenty of other policies to talk about - it won't just be about Brexit and referendums.

A bit more from Labour's shadow transport secretary. He's asked about the political row over the release of London Bridge attacker Usman Khan.

Mr McDonald says he agrees with Tory Justice Secretary Robert Buckland that "we have got to get the tone right and have a sensible, intelligent and informed discussion."

He says he is "very well aware" of the comments from Jack Merritt's father critcising the response from politicians to the attack, and adds that he thinks a "knee-jerk response is not the right way" to deal with it.

Asked whether the government was right to review the 74 convicted terrorists who have been released early, Mr McDonald replies: "I'm open to that. I think that makes sense."

We mentioned earlier that Boris Johnson has cancelled his planned election visit this morning - well, we can now report that he will attend the vigil for victims of the London Bridge attack at Guildhall Yard instead.

Shadow transport secretary Andy McDonald says Labour's plan to slash rail fares by 33%, simplify ticket prices for part-time workers and make train travel for under-16s free is a "much overdue" set of measures.

A simpler London-style ticketing system would also be rolled out across the whole country, he adds.

The money will come from the revenue raised by road tax - "We are repurposing that fund," as he puts it.

Pressed on whether this means planned upgrade work for roads across the country - for example the A1 North - will still ago ahead if money for them is redirected elsewhere, Mr McDonald does not commit to whether they will still go ahead or be axed.

"We cannot road build our way out of a climate emergency," he argues.

Mr McDonald says Labour's plans will make "a major contribution" towards encouraging the shift from cars to public transport.

Another little heads-up. The SNP's Nicola Sturgeon will be the latest leader to take part in a live election Q&A on BBC Radio 5 Live and the News Channel from 09:00 GMT.

We'll be keeping an ear across the whole thing, bringing you key exchanges and clips.

It's put to Robert Buckland, the justice secretary, that the reason London Bridge attacker Usman Khan was released early was in part due to the Court of Appeal reviewing and changing his sentence.

"The Court of Appeal applying a law that had been an amended by the Labour Party of 2008," replies Conservative Mr Buckland.

"Since that time the Conservatives amended the law on several occasions to end or reduce the use of automatic release."

The BBC's assistant political editor feels it could be quite hard to accuse the last Labour government of being "soft on terror"...

Justice Secretary Robert Buckland says his department, as well as the police and security services, are "all working together" to review the cases of the 74 people who have been jailed for terror offences and subsequently released early.

He says it's a "combined approach" with the individuals actually being met in person, as well as their licence conditions being reviewed.

Challenged over the comments by the father of London Bridge attack victim Jack Merritt - saying his son would not wish his death to be used as the pretext for more draconian sentences - Conservative candidate Mr Buckland says: "We need to pause and get the tone right."

But he adds that public protection must be put "first and foremost" and is the "number one priority".

He says the prime minister "was right to say that he wants us to look again at the sentencing of terrorism offences".

The BBC is producing a series of video guides to help you understand key issues and policy areas in this election campaign.

In our latest, our colleague Joey d'Urso tells us how to make sense of polls.

Further to that mention a short time ago of how Labour says it would pay for its rail fares pledge, it's worth noting that the promise is not in the party's manifesto. It's also not in the costing document published alongside the manifesto.

Labour estimates the policy will cost £1.5bn per year, which would come from existing Department for Transport budgets - specifically vehicle excise duty.

The manifesto simply says "Labour will deliver improvements for rail passengers by bringing our railways back into public ownership, using options including franchise expiry.

"This will enable us to make fares simpler and more affordable, rebuild the fragmented railways as a nationally integrated public service, cut the wastage of private profit, improve accessibility for disabled people, ensure safe staffing levels and end driver-only operation."

Nick Hardwick, the former chair of the Parole Board of England of Wales, spoke to Today earlier.

He was talking about the debate around the London Bridge attacker Usman Khan who had previously been convicted of a terrorism offence.

Mr Hardwick resigned from his post in 2018 after a decision by the Parole Board to release black cab rapist John Worboys was quashed.

Speaking to 5 Live Breakfast, Andy McDonald says Labour's plans to cut fares are necessary because of the "swingeing increase" passengers have seen since 2010.

"We're going to try to put that right," he says.

The Labour candidate also defends the plans against charges they would affect funds for road-building - the party has said the money to pay for fare cuts would come from vehicle excise duty.

He says: "There's an awful lot of money available for roads, there's £30 billion ascribed to it by the Conservatives, and there's a whole host of other funds.

"I'll be straightforward with you, you cannot road-build your way out of a climate crisis."

However, he also says Labour hasn't decided what road projects would be scrapped but isn't "in the business of taking up vast swathes of countryside with brand new motorways".

Fifty years ago, the way people voted in the UK was largely determined by social class - but that's not necessarily the case now. Different influences are at play in the 21st Century.

Read polling expert Professor Sir John Curtice's fascinating piece on people's voting trends, originally published last week.

Will climate change feature in the campaign today given the stark warning being issued today by UN Secretary General António Guterres?

He says "the point of no return is no longer over the horizon" when it comes to global warming and there must be "more ambitious national commitments" in the next 12 months.

Mr Guterres spoke as political leaders and climate diplomats meet in Madrid for two weeks of talks.

Remember, Channel 4 held an election debate wholly focused on climate change last week, but not every party sent their leader to take part...
